After years of advocacy, Thailand may become the first country in Southeast Asia to legalize same-sex marriage.

Thirty-seven countries currently recognize same-sex marriage on a national level, and Thailand may soon become the 38th. On December 21, 2023, a package of bills including the Marriage Equality Act was introduced by the cabinet, and debates began in Thailand’s House of Representatives, the lower house of Thailand's legislature. This body resoundingly assented to marriage equality in late March, although it is not yet law.

The Marriage Equality Act would amend Thailand’s civil and commercial code, making many terms that refer to people gender neutral. If the bills pass the the Senate, and receive approval from the King, Thailand will become the third country in Asia and the first in Southeast Asia to legalize same-sex marriage.

Four hundred out of 415 members of the House of Representatives voted to pass the Marriage Equality Act on March 27, 2024. The Marriage Equality Act passed the first reading in the Senate with another overwhelming majority on April 2, 2024.

For decades, LGBTQIA+ laws in Thailand have not matched the country’s acceptance of LGBTQIA+ culture and travelers. Despite being home to many LGBTQIA+ spaces, such as bars and nightclubs, and serving as a destination for many to receive gender-affirming care, discrimination continues and many LGBTQIA+ rights in Thailand remain unprotected. 

While there has been progress in advancing LGBTQIA+ rights in Thailand with the passage of the Gender Equality Act in 2015, currently non-binary and transgender people’s identities are not recognized and LGBTQIA+ couples are unable to marry and struggle with adoption. 

The recorded history of the LGBTQIA+ community in Thailand dates back to the 14th century. These records include verbal accounts and murals depicting LGBTQIA+ relationships. However, in the 19th century, the criminalization of homosexuality and Victorian norms of propriety spread along with European colonialism in the region, although Thailand itself remained independent. 

This influence resulted in a cultural shift, as people began to equate sexuality with moral conduct and consider sexuality taboo. Despite this, Thailand has been famously receptive to LGBTQIA+ travelers, with the Thai Tourism Authority promoting Thailand as a “gay paradise”. 

As LGBTQIA+ visibility and activism have increased, Thai political figures have begun to follow suit, with the Pheu Thai party making marriage equality a main goal. Since taking office in 2023, the Pheu Thai party has been integral in moving Thailand toward equality for LGBTQIA+ people. 

The Marriage Equality Act will undergo its second and third Senate readings in July. If passed, it will be brought to the King for assent, and will then be established within 120 days, making Thailand a role model for the advancement of LGBTQIA+ rights.
